JPS592080Y2 - Support device for mechanical units to be installed and removed - Google Patents

Description

[Detailed description of the invention] This invention is a mechanical unit that must be attached and detached when a heavy mechanical unit is attached to and detached from the machine body, such as when installing and removing the engine from the car body in a cab-over type car. It relates to a device for supporting.

Traditionally, when this type of heavy mechanical unit is attached to and removed from the machine body, the mechanical unit has been supported by supporting multiple locations at the bottom of the mechanical unit via multiple jack heads of conventional jacks. However, such well-known support systems have multiple jacks operating independently of each other, which can easily lead to unstable support of the mechanical unit, which is dangerous, and requires multiple operators. When the mechanical unit is removed, a separate transportation means must be prepared in order to move the removed mechanical unit to a position away from the machine body, which has the disadvantage of poor workability.

The support device of this invention was devised for the purpose of eliminating such drawbacks, and as illustrated in the drawing, it has a lifting means (
A support cart 21 having a plurality of support parts 23 that can support and engage mechanical units to be attached and detached is removably engaged and supported on the lifting head 13 of the lifter 11.

In the support device of this invention having such a configuration, when the mechanical unit is removed from the machine body, the lifting means 11 is operated in the direction in which the lifting head 13 is raised directly below the mechanical unit in the machine body. The support cart 21 supported on the lifting head 13 is raised to bring the plurality of support parts 23 into close support engagement with the lower part of the mechanical unit.

In this state, proceed with the removal work of the predetermined mechanical unit from the machine body, and after making the mechanical unit free from the machine body and fully supported on the support cart 21, the lifting means 11 is operated in reverse. Then, the support cart 21 supporting the mechanical unit is lowered onto the service floor, and the mechanical unit is separated from the main body of the machine.

Thereafter, the support cart 21 is separated from the lifting head 13 of the lifting means 11 as required, and then the support cart 21 supporting the mechanical unit is transported to an appropriate position via the wheels 25.

On the other hand, when installing the mechanical unit to the machine body,
Immediately below the part of the machine body where the mechanical unit is to be attached, the support cart 21 supporting the mechanical unit is raised by operating the elevating means 11, and the mechanical unit is fed to a predetermined position on the machine body.

In this state, after the unit is attached to the machine body, the lifting means 11 is reversely operated, and the empty support cart 2 is
Lower 1.

As is clear from the above, according to the supporting device of this invention, the mechanical unit to be attached and detached is firmly supported via the plurality of supporting parts 23 provided on the support cart 21, so that the mechanical unit is stably supported. The system is safe, the support operation can be carried out by one operator, and since the support cart 21 is removably supported on the lifting head 13 of the lifting means 11, it can be removed from the main body of the machine. The mechanical unit can be moved as it is via the support cart 21 to an appropriate position.

Although the elevating means 11 in the support device of this invention can be constructed with a non-traveling jack without wheels, it is preferably constructed with a traveling jack with wheels 15 like the illustrated garage jack. .

When such a traveling jack is used, the device can be moved to any desired position, resulting in good workability.

In addition, in the supporting device of this invention, the removable holding support on the lifting head 13 of the lifting means 11 of the support cart 21 is provided by a vertical hole 1 provided in the lifting/lowering head 13 as shown in the figure.
Advantageously, this is done via a fit between the vertical axis pin 7 or the vertical axis pin 27 or the vertical hole provided in the lower part of the support carriage 21.

With such a structure in which the vertical shaft pin and the hole fit and engage, support of the support cart 21 on the lifting head 13 of the lifting means 11 and release of the support can be performed only by raising and lowering the lifting head 13 of the lifting means 11. be able to.
